RF Filters types

RF filters are a key component in practically any signal chain. Depending on the application, it is an essential component in order to filter out noise and unwanted signals, limit a transmit signal in order to prevent interfering with other signals or isolate channels in a transceiver.


  • Ceramic filters
  • Mono-block filters
  • Cavity filters up to 40GHz
  • Helical filters
  • Crystal filters
  • SAW filters 
  • WG filters
  • LC filters

RF Low, High and Ultra-Wide Band pass filters

Up to 110GHz filter components and band pass filters, low pass filters and high pass filters used in broadband RF & Microwave and communication systems.



  • Frequency range: From 0.2 up to 110GHz.
  • Bandwidth: up to full waveguide bandwidth
  • Insertion Loss: 0.1 to 1 dB
  • VSWR: 1.5:1 typ


Spacek Labs offers both custom and standard designed active and passive multipliers in a frequency range of 10 to 110 GHz.  MIL-Spec or Space-Qualified units are also available.


The active multiplier line includes 2 thru 8 times multiplication factors operating all the way through W-band. The passive multiplier line utilizes variable-resistance Schottky barrier diodes as the non-linear element to create multiplication factors of 2 thru 4 times. All passive multipliers are of balanced configuration to suppress undesired harmonics, unconditionally stable for any input/output VSWR and they cover complete waveguide bandwidths.


Multipliers are available in:

  • Full Band & Sub-Band Active Multipliers
  • High Power Multipliers, Passive Multipliers

Standard Features:

  • 10 to 110 GHz
  • Balanced Circuitry
  • Compact Size
  • Removable coaxial Connectors or Waveguide Flanges
  • Modular Design
Broadband Detectors

Broadband Detectors

Spacek Labs broadband detectors are extremely rugged and compact and can also be used as harmonic mixers to extend frequency counters to 110 GHz.


By Combining a conventional waveguide technology with planar techniques, Spacek Labs detector offers a full waveguide bandwidth detector that utilizes a zero bias GaAs beam lead diode or GaAs beam lead mixer diode.

Standard Features:

  • RF Bandwidth: Full Waveguide Bandwidths from 18 to 110 GHz
  • Sensitivity: 1500 to 3000 mV/mW (typ)
  • Flatness: ± 1.5 dB (max)
  • Input/Output: Waveguide Flange/SMA(F)
  • Polarity: Positive or Negative
  • Input Power: +18 dBm max
  • Tangential Sensitivity: -45 dBm in a 2 MHz video BW
  • Operating Temperature Range: -55°C to +85°C
